If you already have your password on your email changed, and if you changed your password into something more secure than what your previous password was, I'd say you're pretty safe in terms of hacking, together with your 2FA on your LBC account. However in the event of security compromises on LBCs end, there is still a possibility that your funds will be lost if the hacker knows his/her way around the site. Generally, 2FA-protected accounts are secure as long as you don't lose your device for confirmation or your email which is connected to your account isn't compromised in any way.
